Autophagy alleviates LPS induced Hyper-Permeability of Caco-2 cells by regulating claudin-2 protein
To investigate the effect of autophagy on claudin-2 in lipopolysaccharide (LPS) induced hyper-permeability of intestinal epithelial cell. In human colon cancer cell line (Caco-2), the model of intestinal epithelial injury induced by LPS was established, which were LPS group, LPS combined with inhibitor of autophagy (3-Methyladenine, 3-MA) and control group. Transepithelial resistance (TER) was ...
متن کاملRoles of claudin-2, ZO-1 and occludin in leaky HK-2 cells
BACKGROUND Claudin-2, ZO-1, and occludin are major components of tight junctions (TJs) in the proximal tubule. However, their roles in maintaining paracellular permeability as leaky epithelia have yet to be defined. METHODS To investigate the contributory role of TJ proteins in the leaky proximal tubule, we xamined the effect of inhibiting claudin-2, occludin, and ZO-1 expression on transepit...
متن کاملRab14 regulation of claudin-2 trafficking modulates epithelial permeability and lumen morphogenesis
Regulation of epithelial barrier function requires targeted insertion of tight junction proteins that have distinct selectively permeable characteristics. The insertion of newly synthesized proteins and recycling of internalized tight junction components control both polarity and junction function. Here we show that the small GTPase Rab14 regulates tight junction structure. In Madin-Darby canin...
متن کاملBiochemical and biophysical analyses of tight junction permeability made of claudin-16 and claudin-19 dimerization
The molecular nature of tight junction architecture and permeability is a long-standing mystery. Here, by comprehensive biochemical, biophysical, genetic, and electron microscopic analyses of claudin-16 and -19 interactions--two claudins that play key polygenic roles in fatal human renal disease, FHHNC--we found that 1) claudin-16 and -19 form a stable dimer through cis association of transmemb...
متن کاملRole of claudin interactions in airway tight junctional permeability.
Airway epithelial tight junctions (TJs) serve to separate the external and internal environments of the lung. However, the members of the claudin family that mediate this function have not been fully delineated. We characterized the claudin expression in normal airways removed from human donors during lung transplantation and determined the contribution of each claudin to airway barrier functio...
